Abstract: The present invention provides an hermetic electric compressor capable of stably supplying oil to a compression chamber with a low noise level. The hermetic electric compressor has a closed vessel, an electric element, a compressing element that is disposed over the electric element and driven by the electric element, and an oil reservoir. The hermetic electric compressor also has an oil supply mechanism for supplying the oil from the oil reservoir to the compressing element in the closed vessel, and a suction muffler that communicates with a refrigerant suction part for sucking a refrigerant into the compressing element and is formed of a box body having a predetermined spatial volume. The suction muffler is positioned below the position where the oil is supplied into the closed vessel, and the box body has at least one oil suction port used for sucking a predetermined amount of oil.

Abstract: PROBLEM TO BE SOLVED: To prevent wearing of a sliding portion and lowering in freezing performance due to incomplete sealing, by stably supplying a suitable amount of oil into a compressing chamber and sufficiently lubricating between a piston and the compressing chamber, in a sealed type electric compressor. SOLUTION: Oil is made to flow down from a cylinder block to a suction muffler upper surface 148. An oil sucking hole 143 and an oil reservoir 150 are provided on an electric element side surface 146, thereby controlling the flow of the oil dripping from the cylinder block to the suction muffler 140 and stably supplying a suitable amount of the oil into a compressing chamber.

Abstract: PROBLEM TO BE SOLVED: To provide a valve device having low cost and high reliability in a valve device of a compressor to be used for a cooling cycle. SOLUTION: A discharge read valve 21 provided with a bent part 21a is so arranged as to be pressed by a groove part 25a of a stopper 25 fixed on a valve plate 2 having such a shape as to be engaged with the bent part 21a, and therefore, low cost can be achieved without reducing the efficiency of a compressor, and high reliability can be realized by absorbing and reducing the unnecessary motion other than the opening and closing motion of the discharge read valve 21.
